Abstract

original image

Anchor aweigh! The synthesis and evaluation of new nitrocatechols for surface modification and tractable release on TiO2 are reported (see scheme). The properties of catecholate anchoring and nitrophenyl-based photocleavable release were merged to create a new tool for surface immobilization and controlled release of small molecules, which was investigated on caged fluorophores as proof-of-principle.
